Details

This function is a wrapper around the lower-level
segmentation function segmentByGFLars. It can be run
on p-dimensional, piecewise-constant data in order to defined a
set of candidate change points. It is recommended to prune this
list of candidates using dynamic programming
(pruneByDP), combined with a selection of the best
number of change points. The jointSeg function
provides a convenient wrapper for performing segmentation, pruning
and model selection.

For the specific case of DNA copy number data segmentation, see the
dedicated wrapper PSSeg.

The default weights √{n/(i*(n-i))} are calibrated as
suggested by Bleakley and Vert (2011). Using this calibration,
the first breakpoint maximizes the likelihood ratio test (LRT)
statistic.
